Abstract (en)
[origin: EP3651353A1] When contactors (9) are in an open state and a rotating electrical machine (80) is in a rotating state, an inverter (10) is controlled to appropriately stop operation of the inverter (10). An inverter control device (20) that controls the inverter (10) of a rotating electrical machine driving device (2) including: the inverter (10) connected to a direct-current power supply (11) through contactors (9) and connected to the alternating-current rotating electrical machine (80); and a smoothing capacitor (4) performs, when the contactors (9) are in an open state and the rotating electrical machine (80) is in a rotating state, full active short circuit control that brings an upper-stage-side switching element (31) and a lower-stage-side switching element (32) for at least one phase among switching elements (3) for a plurality of phases in the inverter (10) into an on state to allow current to flow back between the rotating electrical machine (80) and the inverter (10).
